HOSIERY-DRYING FORM.

Application filed August 26 which form a part of this specification.

This invention relates to an improvement in drlers, and moreparticularly to devloes for drying hosiery and similar articles,

which are dried on shaping forms.

One of the objects. of my invention is to provide a device of thischaracter comprising a drying chamber which is arranged to hold aplurality of independent drying forms. I

Another object of my invention is to so support the forms that each ofthe forms may be withdrawn from. the chamber and returned theretoindependent of the others.

Still another object of my invention is to provide a separate closurefor the chamber for each form, and which is supported directly onchamber walls or frame independent of the form supporting devices, sothat the closures may be moved to their closed positions, regardless ofwhether the forms are within or outside of the chamber.

A further object of my invention is to provide automatic closureactuating mechanism under control of the form supports, which isarranged to be actuated at both ends of the movement of the formsupporting devices, to open the closure at the beginning of the movementof the form and close it at the end of its movement, when the form ismoved into or out of the chamber.

The device illustrated comprises a drying chamber, having end and sidewalls, and a top formed of a plurality of pivoted slats, there being aslat for each form. The forms are staggered with relation to each otherand are mounted on supports which are journaled on rods or shaftsextending along the side walls of the drying chamber, onea half beingpivoted along one side while the other half is pivoted along the otherside. The closures are pivoted on transverse axes and each is actuatedby mechanism which is in turn actuated by the form support for the formin line therewith.

The precise nature of my invention will be best understood by referenceto the draw- 1922. Serial No. 584,410.

ings which will now be described, it being prermsed, however, thatvarious changes may be made in the details of construction andarrangement of-the parts without departing from the spirit and scope ofmy invention as defined in the appended claims.

Fig. 7 is an end view of Fig. 6.

The drying chamber is formed of a bottom 10, side walls 11 and end walls12.

The top of the chamber is formed of a plurality of slats 13, each ofwhich is provided with a trunnion 14 at each end, which are pivoted inopenings in the side walls 11, of the chamber. One of the longitudinaledges of each of the slats is provided with a flange 15 while the otheredge is provided with a reversely extending flange 16, and 17 is acounter-weight on the flange 16. When the slats are closed the edges ofadjacent slats overlie and underlie each other respectively as shown inFig. 6, and in which figure the central slat is shown in its openposition. 18 are stop pins for the slats,

which are arranged to be engaged by the counter weights 17 when theslats are open and 19 are similar ins which form supports for the slatswhen closed.

Mounted in the ends of the counter weights 17, are spring pressedplungers 20, see Fig. 7 which press upon the side walls 11 for thepurpose of frictionally retarding the movement of the slats.

The side walls which are made of sheet metal are reinforced by angleirons 21 on the inside thereof and are also provided with vertical slots22, for the forms as hereinafter described. As the forms are staggeredwith relation to each other as shown in Fig. 1, the slots in one sidewall are also staggered with relation to the slots in the other sidewall.

The side walls are also reinforced on th exterior by means of verticallydisposed channel members 23, which also form guides for the slotactuating yokes hereinafter described.

Supported by brackets 24 are fixed shafts 25, which extend along thesides of the structure, and pivotally mounted on each of these shaftsare a plurality of form supports 26. Each support is provided with aturn table having a rotatable member 27 to which a hosiery drying form28 is secured. This turn table is arranged to permit the form to beturned about an axis perpendicular to the axis of the support 26 topermit the operator to adjust the stocking on the form. 29 is a detentfor frictionally latch ing the form in its proper position for entranceto the drying chamber.

Slidably mounted in each channel member 23, is a yoke 30 having an upperrack 31 and a lower rack 32. 33 are pinions which are connected to thetrunnion 14 of the slats, there being one pinion on each slat whichcoacts with its yoke. These yokes are ar- L ranged to slide between theflanges of their channel members which form side "uides therefor, bottomguides being formed by the webs between the flanges of the channelmembers, while the top guides are formed by covers 34, which extendbetween engage the free edges of the flanges of the channel members.

Each yoke is provided with upper actuating projections 35 and 36 atright angles to each other, and similar lowerprojections 37 and 38.These projections are engaged by dogs 39 and 40, the one being mountedon the hosiery form 28 while the other 15 mounted on a counter weight 60on the support 26.

The dog 39 is provided with engaging hooks 41 and 42 for engaging theprojections 35 and 36, respectively, while the dog is provided withsimilar hooks 43 and 44 for engaging the projections 37 and 38,respective y.

The actuating mechanism between the form holders and the slats are allthe same so that it will only be necessary to describe the manipulationof one of the forms, with particular reference to Fig. 4, in which allof actuating devices are clearly shown.

When the form is in the drying chamber the hooks 41 and-42 are engagedwith the, projections 35 and 36, and the rack 31 is in engagement withthe pinion In removing the form from the drying chamber, the counterweight or the support 26 is depressed to swing the support about shaft;-25. At the beginning of the upward movement of the form 28, theprojection 42, will elevate the yoke 30 a suflicient distance to ro tatepinion 33 clockwise to swing the slat 13 into its open position ahead ofthe form 28. As the form 28 approaches the upright position shown atflie right side of Fig. 1, hook 43 of the dog 40 will engage projection37 and still further elevate yoke 30.

During this further elevation of yoke 3o, rack 32 will rotate pinioncounter clockwise and swing the slat to its closed position, to preventthe escape of hot air during rest on the reinforce 21, (which also formsa support forms when in the drying chamber) the hook 41 will engageprojection 35 and shift the yoke 30 to its extreme lower position andduring such movement the pinion 33 will be rotated counter-clockwise andclose the slat'13 immediately after the form is moved into the dryingchamber.

Mounted in the lower portion of the drymg chamber are headers 50, shownat the left side of Figure 2, at one end and 51, 51 are similarheadersat the other end shown at the right side of Figure 2. The headers Justbefore the form reaches its position of at one endiare connected to theheaders at.

the other end by pipes 52, 52,.to form two steam radiators one above theother, 53 are steam inlet pipes extending into headers 50, havingsuitable control valves, and 54 are water outlet pipes leading fromheaders 51 51, to a steam trap not shown.

55 is a fan box below the bottom of the drying chamber, butcommunicating therewith and which is provided with'a fan 56, driven inany desired manner. The bottom of the fan casing is provided with inletparts which are controlled by a grid 57 connected to an operating handle58.

Air is sucked in throughthe parts and driven upwardly over the radiatorwhereby it is heated, to the top of the chamber over the stockings ontheforms. This fan will also cause a continuous circulation of air upwardlyfrom the center and downwardly along the sides and ends of the chamber,and-cause the air to pass in a continuous manner over the radiator.

' The operator in charging moves from one ltlO lot;

ing a plurality of drying forms which are arranged to be separatelyremoved from the a drying chamber, together with a closure for thedrying chamber for each form, which is arranged to be closed when theform is in drying position in the chamber or in charging position on theoutside of the chamber.

A so from the provision of automatic means for first opening and thenclosing the drying chamber when the form is moved into either dryingposition or charging position.
